High-strength PC component for prefabricated housing
The invention discloses a high-strength PC component for a prefabricated housing. The high-strength PC component for the prefabricated housing comprises steel plate layers arranged on the upper end face and the lower end face, and a structural inner layer located between the steel plate layers, wherein the structural inner layer comprises concrete layers stacked in parallel sequentially and carbon fiber cloth layers located between the concrete layers; and the structural inner layer further comprises a heat preservation layer located at the bottom of the lowermost concrete layer. The PC component further comprises a steel bar component. Each concrete layer is prepared from the following raw materials in parts by weight: cement, coarse aggregate, fine aggregate, modified rubber particles, polymer emulsion, polymer fibers, a water reducing agent, an air entraining agent, an early strength agent and water. According to the high-strength PC component for the prefabricated housing provided by the invention, the raw materials of the concrete layers comprise the modified rubber particles prepared by modifying waste rubber, and the rubber is soaked with a silane coupling agent, so that the compatibility between the rubber and the cement is enhanced, meanwhile, the crack resistance of the concrete can be greatly improved, and the weight of each concrete layer is reduced.
本发明公开了一种高强度装配式住宅用PC构件，包括设置在上下端面的钢板层和位于钢板层之间的结构内层，结构内层包括依次平行叠放设置的混凝土层和位于混凝土层之间的碳纤维布层；结构内层还包括位于最下层混凝土层底部的保温层；PC构件还含有钢筋构件；混凝土层原料按重量份计包括：水泥、粗骨料、细骨料、改性橡胶颗粒、聚合物乳液、高分子纤维、减水剂、引气剂、早强剂和水；本发明混凝土层原料中包括由废弃橡胶改性制得的改性橡胶颗粒，将橡胶采用硅烷偶联剂进行浸透，增强橡胶与水泥之间的相容性，同时可以大幅度改善混凝土的抗裂性，同时减轻了混凝土层的重量。
